構造体
📘 Microsoft Learn (日本語) · English

HSP用 定義

HSP3.7/3.8 は構造体機能が無いため4byte整数配列(dim)+peek/poke で操作(32/64bitでサイズ・位置が異なる場合はタブで分割)。IronHSP は NSTRUCT(#defstruct/stdim/->)で32/64bit共通。

; HSP3.7/3.8 は構造体機能が無いため、4byte整数の配列変数で操作します。(x64 レイアウト)
; D2D1_ARC_SEGMENT サイズ: 28 バイト(x64)
dim st, 7    ; 4byte整数×7(構造体サイズ 28 / 4 切り上げ)
; point : D2D_POINT_2F (+0, 8byte)  varptr(st)+0 を基点に操作(8byte:入れ子/配列)
; size : D2D_SIZE_F (+8, 8byte)  varptr(st)+8 を基点に操作(8byte:入れ子/配列)
; rotationAngle : FLOAT (+16, 4byte)  st.4 = 値  /  値 = st.4   (lpoke/lpeek も可)
; sweepDirection : D2D1_SWEEP_DIRECTION (+20, 4byte)  st.5 = 値  /  値 = st.5   (lpoke/lpeek も可)
; arcSize : D2D1_ARC_SIZE (+24, 4byte)  st.6 = 値  /  値 = st.6   (lpoke/lpeek も可)
; ※4byte境界の整数は添字 st.N(N=オフセット/4)で読み書き可。それ以外は peek/poke 系を使用。
; IronHSP は NSTRUCT(構造体)をサポート。32bit/64bit どちらでも同じコードで動作します。
; ※GUID・入れ子構造体はデフォルト型でないため、依存する #defstruct を先に定義(下記に同梱)。
